Hi Rowley
Thanks for the details; its possible I could have worded my request a little better. I am trying to learn more about William Lewis and Thomas Rees and family named in the '1873 Will'. It mentions Mary Rees wife of Thomas Rees who was the daughter of William Lewis.
I have located Thomas Rees on the 1871 at Tir Jack (RG10/5389); he is described as Head, Widower, 54 (?) farm labourer, born Gelligaer. Also enumerated are two daughters, Ann, unm, 21, laundress, and Rachel, 17 both born Gelligaer
If this is the right Thomas Rees then he must have married Mary (Lewis) later.
